Russian oil production: Last month(May 2015) saw Russia’s average daily production rise to 10.708m bbd, overtaking Sauda Arabia’s daily average of 10.25m bbd for the same period. The rise is down to an increase in the production of gas condensate and high-quality ultra-light oil, according to analysts. OPEC is due to review its oil production policy at a meeting in Vienna on Friday, June 5.
